RISO means “ideal.”

(And we really mean it.)

The founder of RISO, Noboru Hayama, chose the name of his company for a good reason. It’s Japanese for “ideal.”

RISO strives to create fundamentally unique new technologies in paper-based communication through an approach that emphasizes productivity, cost containment, and versatility. Every product we manufacture delivers these benefits in a balance that offers the ideal solution to our customers.

At the same time, RISO carries on a tradition of caring for the world at large through our environmental and community support programs. Just as we are committed to delivering the ideal products and service, we strive to be an ideal corporate citizen in every country in which we conduct business.
